Dialog: Conjugate-Cam-FB

Conjugate-Cam FB

See: Add Conjugate Cam FB.

Why use a Conjugate Cam FB?

Typically, to do the force and stress analysis of a 2D-Cam, you will select one 2D-Cam as the Power Source in the Configure Power-Source dialog-box.

However, if there are two Cams (called Conjugate Cams) that drive the same follower system, you must add and configure a Conjugate Cam FB. Then select it as the Power-Source in the Configure Power-Source dialog, before you can do the force and stress analysis correctly. If you do not use and configure a Conjugate Cam FB, the Contact-Force will not move from one cam.

2D-Cam - work-flow

1.Add a 2D-Cam - see Add 2D-Cam

If the new 2D-Cam is a Conjugate-Cam or a Groove-Cam (or other Body-Closed Cam):

1.a. Add a Conjugate-Cam FB - see Add Conjugate Cam FB

1.b. Edit the Conjugate-Cam FB - add 2×flanks from 2×2D-Cams - You are Here

2.Select the 2D-Cam or the Conjugate-Cam as the Power Source for the Follower's kinematic-chain - see Configure-Power Source

3.Review the 2D-Cam : Display, Properties, Life, ... - see below

4.Add a Cam-Data FB - see Add Cam-Data FB

5.Edit the Cam-Data FB to link it to the 2D-Cam- - see Link the Cam-Data FB to a 2D-Cam

6.Connect wires from the Cam-Data FB to a Graph FB to analyse 5 parameters

7.Edit the Cam-Data FB again to Calculate the Cam-Coordinates - see Cam-Coordinates dialog

How to open a Conjugate Cam dialog-box


To open the Conjugate-Cam dialog-box:

1.Double-click the Conjugate-Cam FB


1.See How to Open a Dialog-Box  

The Conjugate-Cam dialog-box is now open.

Note: if you want to analyse the forces of a Groove Cam - you MUST add 2 x 2D-Cams to the model. The Cam-Follower Rollers will be above each other.

You cannot use the Inner and Outer Flanks of 1 x 2D-Cam.

Select to add TWO 2D-Cams

In the graphic-area or Assembly-Tree:

1.Click a 2D-Cam

2.Click a different 2D-Cam


The two 2D-Cams must be capable of being the Power-Source to the same Cam-Follower Part

Each 2D-Cam drives the Inner-Cam-Flank OR the Outer Cam-Flank.

3.Click OK-tiny-11-15 to close the dialog-box.

Note 1 : If the 2D-Cams you select do not drive the same Follower-Part, you will get this message in the Feedback Area.



To do Force Analysis of the Conjugate Cams, you must select the Conjugate-Cam FB in the Configure Power Source dialog-box.

To remove a 2D-Cam

1.Select the 2D-Cam in the list
